In an inland multi-bridge waterway, vessel behaviors are influenced and restricted by various factors such as people, ships, environment and management etc.; the behaviors are always different with the temporal and spatial change; it is also difficult to use accurate mathematical model to describe the behaviors; and moreover water traffic is not suitable for experiments using real vessels. Hence people...
The waterway regulation in Jingzhou has been implemented since 2013, the south branch of the waterway in the Jingzhou Yangtze River Bridge was open as a temporary channel for engineering ships. Based on the utilization of the waterway, this work analyses the navigational efficiency improving measures by using the queuing theory. According to the dynamic calculating feature of the used theory, the...
Routing and manoeuver planning are accepted tasks of deep sea vessel navigation to increase the safety on sea and to improve the time- and resource efficient transport of goods and passengers. Trajectory optimization of inland water vessels is a similar navigational task intended to ensure a safe passing of bridges and an efficient locking of vessels. A resilient provision of position, navigation,...
Firstly this paper classifies Changjiang river's shipping goods into three kinds: public goods, quasi-public goods and private goods according to goods classification criterion of competitiveness and exclusiveness and establishes its characteristics' mathematical model, thinking that Changjiang river's shipping goods is a complex of three kinds of goods and its characteristics is not static and fixed,...
A new maritime navigation system based on a laser range-finder scanner for obstacle avoidance and precise maneuvering operations is described in this paper. The main novelty of this work is the adaptation and implementation of known technology for laser range finding and algorithms for target tracking into a system that operates in real time and has been tested in different natural sea and inland...
